Python Tutorial for Beginners p.15: Mutability - Definition & Potential Problems and their Solutions

In this series, we will go over my notes for Python. And in this video, we are going to cover mutability. We will see how immutable and mutable objects are defined. We will go over different situations where mutability might cause a problem and how to deal with it. And will we see how mutability works when using nested data structures.
